Você pode fazer chamadas de API escolhendo o método HTTP e definindo parâmetros opcionais:
$facebook->api('/me/feed/', 'post', array(
'message' => 'I want to display this message on my wall'
));
Enviar postagem para o mural do Facebook:
Inclua o arquivo fbConfig.php para conectar a API do Facebook e obter o token de acesso.
Postar mensagem, nome, link, descrição e a foto serão enviados ao mural do Facebook. O status de envio da postagem será mostrado.
Se o token de acesso do FB ($ accessToken) não estiver disponível, a URL de login do Facebook será gerada e o usuário será redirecionado para a página de login do FB.
Postar no mural do Facebook php sdk
<?php
//Include FB config file
require_once 'fbConfig.php';
if(isset($accessToken)){
if(isset($_SESSION['facebook_access_token'])){
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}else{
// Put short-lived access token in session
$_SESSION['facebook_access_token'] = (string) $accessToken;
// OAuth 2.0 client handler helps to manage access tokens
$oAuth2Client = $fb->getOAuth2Client();
// Exchanges a short-lived access token for a long-lived one
$longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
$_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;
// Set default access token to be used in script
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
